IMPROVEMENT IN HOISTING AND DUMPING COAL.

Specification forming part of Letters Patent No. 59,243, dated October 30, 1866.

To all whom it may concern:

Be it known that I, GEORGE MARTZ, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Hoisting and Dumping Coal; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation ofthe invention, suf'cient to enable one skilled in the art to which it is allied to construct and use the saine, reference being had to the accompanying drawings, which are made part of this specication, and in which- Figure l isa perspective view. Fig. 2 is a rear elevation.

rlhe improvement in dumping, by the contact of the forward end of the car-platform with the breast of the dumpingchute.

The arrangement of the openings in the guides which, at the required moment, admit the slides to pass through them, as the platform is tilted, in other posit-ions maintaining the car in a horizontal position.

The construction of the platform, whose curved face bears against the breast of the chute as the bed is tilted, preventing forward jar of the coal-car or racking of the guides as the car turns on its axis.

In the drawings, A A are the high supporting-rails, upon which the car runs, the blocks L or the platform filling the gaps M when the platform is down. y

As the gate D is lifted the blocks L rise upbetween the wheels, so as to keep the car from rolling, and the guide O slips inthe groove F in the sides of the gate.

the platform supporting the forwardend of the car, which presses against them.

The return motions are obtained by lowering the gate of the platform, as before, the platform turning on its axis in the portion P of the gate, which is lowered into position to allow the empty car to be run of and a full one substituted.

Having described my invention, what I claim therein as new, and desire to `'secure by Letters Patent, is- 4 l. The combination of the platform, con-v structed and operating as described, with the breast of the chute, which tilts the rising platform into an inclined position.

2.- rlhe arrangement of the sectionblocks L L and the gaps N in the guides, operating as described.

3. The curved face to the platform, acting in combination with the supporting-breast H, as and for the purpose described.

GEORGE MARTZ.
